1-Deamidino-, 3-deamidino- and 1,3-di(deamidino)dihydrostreptomycin (1, 2, 3) were prepared by treatment of dihydrostreptomycin (DHSM) with ammonia at 100 degrees C. The 3-guanidino group of DHSM is suggested to be more important than the 1-guanidino group for the antibacterial activity of DHSM. 1-N-[(S)-4-Amino-2-hydroxybutyryl) and 1-N-[(S)-4-guanidino-2-hydroxybutyryl] derivatives (4, 6) of 1-deamidinodihydrostreptomycin were futher prepared.
通过在100℃下用氨处理二氢链霉素(DHSM)制备了1-脱脒基-、3-脱脒基-和1,3-二(脱脒基)二氢链霉素(1、2、3)。对于DHSM的抗菌活性,有人认为DHSM的3-胍基比1-胍基更重要。进一步制备了1-脱脒基二氢链霉素的1-N-[(S)-4-氨基-2-羟基丁酰基]和1-N-[(S)-4-胍基-2-羟基丁酰基]衍生物(4、6)。
